The film was dedicated to two veteran Australian actors who were to have been in the cast but died before the film was released - Frank Thring and Shelia Florence. Their roles were eventually played by John Flaus and Esme Melville.
This film is considered an "Ozploitation" (Australian exploitation) picture.
One of only a handful of Australian horror feature films which are vampire movies. These titles are: Thirst (1979), Bloodlust (1992), The Wicked (1987), Queen of the Damned (2002) and Daybreakers (2009). What We Do in the Shadows (2014) was from neighbouring nation New Zealand.
